Why is water important 3 reasons?
Why Is Water So Important to Life on Earth?
- Oxygen. Plants deserve appreciation for producing breathable air and for what they are able to do with water.
- Weather. Global patterns of weather and precipitation are dictated by the movement, quantity and temperature of water, both in the ocean and in the atmosphere.
- Agriculture. ...
- Fisheries. ...
- Sustainability. ...
What is wastewater treatment?
Wastewater treatment removes the solids and cleans the water. The end product is effluent, a relatively harmless water source that can either be returned to a natural water supply or treated further to make it suitable for eating and drinking.
What is waste water?
Wastewater is any type of water that has been contaminated, whether that’s by using it in your dishwasher, laundry machine, shower or toilet, or in a commercial process. Once the water is used, it’s contaminated with byproducts like soap, sewage, food, chemicals and more.
Is water a natural resource?
As you know, water not only makes up the bulk of the planet, but it also makes up the bulk of the human body. Our lives and environment specifically rely on having clean, safe water to drink—and if we fail to treat it properly, we’re squandering a precious natural resource.
1. Benefits environment
Since all the water waste is released in natural water reservoirs such as lakes and rivers, the water gets contaminated. This polluted water is consumed by fishes, crops, and animals. Also, the polluted water is evaporated and ultimately the rainwater is also nothing but polluted water.
2. Recycled water
Since factories and industries require a huge amount of water every day for different processes, water recycling is the best solution. Any water waste treated by plants is pure enough to be utilized again. This process saves hundreds of liters of water.
3. Energy production
The sludge collected during the wastewater treatment process contains a large amount of biodegradable material. These materials can be used to generate electricity and other energy. The energy generated here can be used in wastewater treatment plants making it self-sustainable.
4. Save you from heavy fines
The Government of Maharashtra and MPCB have appointed a special committee to check the progress & violation of wastewater treatment plants. It is vital to understand the importance of wastewater treatment and apply it accordingly.
Why is wastewater treatment important?
Wastewater treatment protects humans and ecosystem. Wastewater contains elements toxic to humans and the ecosystem. Wastewater treatment facilities help to purify the water and eliminate situations like what is currently seen in developing countries .
Why is wastewater important for the ecosystem?
Wastewater treatment also protects the ecosystem. Fish and aquatic life require fresh water. When their water environment is laden with wastewater, they cannot survive. If chemicals, such as nitrogen and phosphates, enter streams, rivers or large bodies of water in excessive amounts, it causes excessive plant growth which release toxins into ...
What is the purpose of wastewater treatment facilities?
Summary. The main goal of wastewater treatment facilities is to protect humans and the ecosystem from harmful and toxic elements found in wastewater. Water treatment facilities were designed to speed up the natural process of purifying water because the natural process is overloaded.
How much of the world's wastewater is discharged without treatment?
Globally, over 80 percent of all wastewater is discharged without treatment. 1 In the countries that do have water treatment facilities, they use various methods to treat water with one common goal: purify water as much as possible and send it back into the environment to keep humans and the Earth safe and thriving.
What would happen if there was no wastewater treatment?
With billions of people and even more wastewater, the natural process is overloaded. Without wastewater treatment, the amount of wastewater would cause devastation, as it still does today in developing countries.
Why is natural water treatment overloaded?
While Mother Nature does her best to naturally process wastewater, there is too much for her to handle. Because the global population is so large and growing, so is wastewater. Nature can’t keep up with naturally processing the excessive amounts of wastewater.
How does wastewater treatment affect the environment?
Wastewater treatment improves and purifies used water to make it fit to use again or send back to the environment. It can flow to surface water (rivers and streams) or to groundwater under the land surface. When untreated wastewater ends up back in the environment it causes water pollution and this affects all living creatures.
When did sewage systems first appear?
The earliest sewage systems first appeared in cities around 3000 BC but this was a luxury that only the rich had the privilege of using! The majority of people dug open pits or emptied chamber pots into nearby rivers, seas or ditches.
How does biofiltration work?
The biofiltration process requires oxygen to work. Oxygen naturally enters the wastewater as it flows through the pipes of a treatment system. We can speed up the whole process by adding oxygen artificially with an air blower. Air blowers create tiny bubbles of oxygen that allow the microorganisms to multiply quicker and break down more waste. Air blowers are well worth installing because they operate and run on low levels of electricity.
What is a septic tank?
A basic septic tank is a watertight chamber through which domestic wastewater flows for primary treatment. Settling and anaerobic processes reduce solids and organics, but not entirely. The remaining solids need to be pumped out for separate disposal. Liquid waste flows through pipes to a site nearby (percolation area) or directly to surface water nearby. However, this basic form of treatment often isn’t enough to prevent water pollution.
Organic matter
Organic matter in wastewater includes proteins, carbohydrates, fats, oils, greases, and synthetic compounds found in certain detergents.
Inorganic compounds
Inorganics in wastewater include compounds with copper, lead, magnesium, nickel, potassium, sodium, or zinc. In many cases, these harmful substances are the byproducts of commercial and industrial activities.
Nutrients
Nutrients in wastewater include nitrogen and phosphorus compounds. These often come from human waste and cleaning products like laundry detergent and dishwasher soap.
Microorganisms
Some microorganisms in wastewater are helpful because they break down organic matter that would otherwise pollute the environment.
